Modern Tower

Back in present day, you now have to find a power source in a New York Skyscraper. First, climb the yellow ladder directly in front of you. Jump along the pipes without touching the ground. Continue on across an air vent. Jump through the gaps in the wall, and swing along the beams.

Continue heading along the packing supplies, and walk through to what looks like a garage. Slide under the door and almost fall into the New York skyline. Turn right, and jump towards what looks like a massive yellow V attached to the wall. Jump over to it, and climb up.

Reach a platform of the crane, then keep climbing up. Work your way around the side of the building using the beams both sticking out of the wall and suspended by ropes. Once you reach a yellow platform that looks like you can't go any further, start climbing up again.

Follow the wires up then to the left then up again. You are now on a much larger platform. Slide under the giant cable reel, then run through the top cylinder. Run along the suspended beam, jump to the giant cylinder of rebar, then continue up to the platform.

Jump over to where the single light bulb is hanging, then run up the slanted wall next to it. Keep going across the beams until you get to the suspended one. Make a big jump out to it, then continue on to the left. You are now at the top of the building, but you have to keep going up.

Climb the first machine directly in front of you. Once that has been scaled, move along the top until you can jump down to the beam with the bright red light on it. Continue straight until you can jump to the lit up crane. Climb to the top of this now. Make your way out to the end of the crane to trigger a cutscene.

Now's the time to jump. Open the parachute when prompted by pressing any button, and steer towards the helicopter landing pad to complete the mission.

ACHIEVEMENT/TROPHY UNLOCKED

But wait! There's something you need to do in the caves before going back into the Animus!

OPTIONAL OBJECTIVE: Plugging Power Source #1

After obtaining the power source, it's time to plug it in! Before entering back into the Animus, take the time to navigate the corridors on the LEFT side. Take the well-lit stairway to the top and approach the pillars to trigger a (unskippable) cutscene with Juno.

Once that's done, go around the pillars using the stairs. Jump and climb up the structure to the top and then jump towards the second floor ledge to trigger a second cutscene with Juno.

Now approach the power source control deck and a cutscene will show Desmond inserting the power source, revealing a new area of the caves for Power Source #2. That's it for now! Feel free to talk to everyone a few times before hopping back in the Animus to begin Sequence 6.
